Understanding the extract and lift functions

Premiere Pro provides two methods for removing a range of frames or a gap from the Timeline: extracting and lifting.

Extracting
Removes frames from the Timeline, closing the gap like a ripple deletion. These frames can be within a single clip or can span multiple clips, but it is important to understand that extracting removes the selected range of frames from all unlocked tracks. You can also extract a gap from the Timeline. This feature works only with a range of frames that have been marked with In and Out points in the Program view.
